Kai Hagbard, your coffee cup is going to have an inch of mold in it (unless you wash it) before H2O can even attempt to meet your challenge. I am far from an expert in ancient religions but even I know Buddha’s date of birth is not known, Krishna’s “date of birth” is not known, and Horus’ “birth date” is not known.
On another forum a Hindu (with little real knowledge of Hinduism) unsuccessfully attempted to prove the authenticity of Hindu Scripture.
On the other hand many of the historical details in the Old Testament have been shown to be true through archeology. Of all the religious writings only the Bible can be demonstrated to contain any real historical truth.
What I find amusing is just how far our detractors will go to draw comparisons between Jesus the Christ and other mythical and real personages who are called gods; even so far as to invent birth dates for mythical beings.
